Minigold
Minigold is a gold-reduced casting alloy. Its composition makes it suitable for a wide range of indications and its golden yellow colour allows natural shade effects in the restoration veneered with laboratory composite SR Nexco.
Indications*
- Onlays, ¾ crowns, crowns
- Telescope crowns, conus crowns
- Bridges
- Wide-span bridges
- Cast posts / cores, bars, attachments
